G=yellow and g=green pea seeds. You cross a heterozygous yellow-seeded plant with a green-seeded plant to produce the F1. In the F1, you find 70 yellow-seeded and 35 green-seeded offspring. Conduct a Chi-squared test. The critical value in the chi squared table is 3.84. What is the calculated Chi-square value? Are your results consistent with autosomal dominance? Explain.
Homework Answers
Gg x gg
Gg, Gg, gg, gg f1 generation
Yellow seeded Gg=70
Green seeded gg=35
Our null hypothesis is both should be in equal proportion
Observed. Expected (O-E) 2 (O-E) 2/E
Gg. 70. 52. 324. 6.23
gg. 35. 53. 324. 6.11
X2=12.34
Critical value from the chi square table is 3.84 at df=1
Our calculated chi square value is much greater than tjis so, our hypothesis is rejected

I’m so confused by this, please explain Punnett Squares Reginald Punnett was a British geneticist who developed the Punnett square to explain how the chromosomes of parents cross and produce offspring. In order to solve genetics problems using a Punnett square, it is necessary to a) understand the associated vocabulary and b) understand some of the rules for solving the problems. · Before you continue with the problems below, review the meaning of the terms allele, dominant, recessive, homozygous, heterozygous,...
